For those issues to happen, a malformed\nwire message is needed to be sent from the device.\n\nInstead of duplicating the bounds checking code already present in\ndecode_message(), use the function inside resp_worker().","modified":"2026-09-26T14:16:00.149105007Z","published":"2026-09-25T11:17:47Z","upstream":["CVE-2026-98155"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98155"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-104799.json"}}],"schema_version":"1.9.0"}
